Reactions of Anilines and Benzamides with a Fourteen-Electron Iridium(I) Bis(Phosphinite) Complex: N-H Oxidative Addition versus Lewis Base Coordination
{{output}}
Anilines react with (POCOP)Ir(C(6)H(5))(H), 12, (POCOP = 2,6-(OPtBu(2))(2)C(6)H(3)) to yield equilibrium mixtures of 12, the Ir(I) sigma-complexes (POCOP)Ir(NH(2)Ar), 13, and the Ir(III) oxidative addition adducts (POCOP)Ir(H)(NHAr), 14. Quantitative studies o... ...
